Frequently Asked Questions
Q: What is the AN-135 connector rated for?
A: The AN-135 is a heavy-duty SB350 connector rated for 350A continuous current and 450A for short durations (1 minute). Maximum voltage is 600VDC, making it suitable for high-power battery and motor applications in electric lift trucks, reach trucks, and forklifts.
Q: What cable size does the AN-135 accept?
A: The AN-135 accepts 2/0 AWG cable. This large gauge is required to safely handle the 350A continuous rating without voltage drop or heat buildup. Do not use smaller cable sizes.
Q: What is the housing material and why does it matter?
A: The AN-135 housing is constructed from polycarbonate (UL94-V0 flame-retardant grade). This material prevents connector failure under high current draw and thermal stress, resists moisture intrusion, and meets safety standards for industrial truck applications.
Q: Are the AN-135 contacts silver-plated and why?
A: Yes, the AN-135 uses silver-plated copper alloy contacts. Silver plating ensures low electrical resistance, reduces contact corrosion, and maintains reliable current flow under high-cycle charging and discharging in electric trucks. This extends connector lifespan and reduces voltage drop.
Q: Which electric truck brands use the AN-135 connector?
A: The AN-135 SB350 connector is compatible with Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and other OEM electric lift trucks requiring 350A-rated battery connectors. Verify your truck model documentation to confirm SB350 compatibility before ordering.
Q: How do I know if the AN-135 needs replacement?
A: Replace the AN-135 if contacts appear heavily corroded, the connector is loose and cannot tighten, the housing is cracked or melted, the truck shows reduced performance or battery charging failures, or you observe arcing or sparking at the connection. Typical lifespan is 8 to 12 years in high-cycle service.
